The purpose of this study is to provide data for the restoration of 'Yongyun(龍淵)' and 'Hwahongmun(華虹門)' through an investigation of the vicinity of their original landscapes at the time of construction of Hwaseong in Suwon and through tracing the transformative process of the environments of this vicinity. The results are as follows; As identified by 'Yongyunjung(龍淵亭)' and 'Yongdugak(龍頭閣)', other names of Yongyun, 'Banghwasuryujung(訪花隨柳亭)', which was built on 'Yongduam', is a facility whose place identity is highlighted with a sense of unity with Yongyun. The south lakefront of Yongyun, bordering Banghwasuryujung, has boundaries that make the best use of the natural geographical features of Yongduam while the current circumference of Yongyun is comparatively shorter than its original state. The size of 'Joongdo(中島)', however, seems to be an example of apparent over-design complement and reorganize 'Joongdo', which had been restored larger than its original state at the time of restoration in the 1970s. The depth of 'Yongyun' was created to be lower than the actual depth, without consideration for its initial depth, as soil was accumulated through continuous flooding after it was created. It is assumed that the original drains which were installed about 10m inside the lake were created facing the stream. As regards the planting environment, a circular planting of willows was made in the outskirts of 'Yongyun', except the 'Yongduam' which is a pure forest, and a mix of 'Pinus densiflora', shrubbery and deciduous broad leaf trees was planted in 'Joongdo'. Of the plants growing in the area of this study, plant species introduced to Korea after Hwaseong was constructed are found, most of which provide interest and attraction. The old pine trees growing in a group once grew in the castle areas of the vicinity even in the 1920s, the period of Japanese occupation, but they disappeared from the area in the aftermath of subsequent urban development and the Korean War. Although restored to the site, the number and space taken up by these trees are insignificant compared to those of the original environment. On the basis of these results, the following is considered necessary for the true restoration of the vicinity of 'Yongyun' and 'Hwahongmun': First, the grounds of 'Yongyun' should be dredged deeply enough to expose the bedrock and should be recreated in the rough outline of a half moon by extension to the southwest toward 'Yongduam' and 'Hwahongmun', and the size of 'Joongdo' should be significantly reduced. Secondly, considering that most plant species, except the pine trees and wild trees in 'Yongduam', are non-native plants introduced in order to provide such attractions such as the appreciation of scenic areas, they should be replaced with native species, mainly with the pine trees which were utilized during the construction of Hwaseong. The weeping willows planted in the 'middle-island' should be relocated to the outskirts of 'Yongyun', and replaced with pine trees as the major trees and maple trees or deciduous broadleaf trees to fill in the gaps. Thirdly, exotic species such as the 'Pinus rigida' planted in a group around 'Banghwasuryujung' and 'Bugammun' and 'Pinus strobus' planted in the vicinity of Hwahongmun' should be removed.

The purpose of this study was to find characteristics of $Pinus$ $densiflora$ forests in previous records and cultural landscape regions and to establish a management method for recovery of $P.$ $densiflora$ landscape. A total of 16 landscape paintings were analyzed to study $P.$ $densiflora$ forests in Inwangsan(Mt.) shown in figure data. As a result of analyzing figure data, $P.$ $densiflora$ $forests$ were found to be distributed mainly in the ridge line of east slope side of Inwangsan(Mt.) from landscape paintings of Jung Seon, Jang Si Heung and Gang Hee Un. In order to analyze the landscape of $P.$ $densiflora$ forests shown in photograph data on Inwangsan(Mt.), photographs of Inwangsan(Mt.) since late 1800s were searched and a total of 24 photographs were used for analysis. As a result of photographic analysis, $P.$ $densiflora$ forests were found to be distributed mainly in the low area and ridge line of western slope side of Inwangsan(Mt.). As a result of analyzing the distribution status of 10 cultural heritages of Inwangsan(Mt.), cultural heritages in the mountain were mainly established with rocks and $P.$ $densiflora$ forests as the background and are establishing their landscape not only as a form of cultural heritage but also including the natural landscape in the background. A method of restoring cultural landscape of P. densiflora forests was necessary. As a result of analyzing 26 rock beds of Inwangsan(Mt.), most of $P.$ $densiflora$ forests were distributed nearby rock beds since the past. Among such regions, restoration and management of introduced species in the accumulated soil regions to $P.$ $densiflora$ forests were deemed necessary. As a result of analyzing current vegetation of $P.$ $densiflora$ forest areas of the past, 51.87% of areas maintained $P.$ $densiflora$ forest and 25.80% were changed to artificial forests. Most of low areas of the mountain were turned into urban area (10.16%). Management type for restoration of $P.$ $densiflora$ landscape of Inwangsan(Mt.) was classified into preservation, $P.$ $densiflora$ restoration and maintenance. Preservation management was configured as $P.$ $densiflora$ distribution and rocky area distribution. The targets of $P.$ $densiflora$ restoration were indigenous broad-leaf trees, vegetation areas with introduced species and damaged regions within the mountain. The targets of maintenance were urban area in the low area of Inwangsan(Mt.) and military base at the top of the mountain.

This study area for this research was the Taereung of the 2009 World Heritage-listed Royal Tombs of the Joseon Dynasty. The Taereung space was divided into that of the royal tomb space, religious service space, transposition space and entry space. The original vegetation is assumed to have been planted at the right, left and backside of the tomb based on historical research literature. Regarding the original vegetation landscape of Taeneung, it was assumed that Pinus densiflora was distributed around the tomb lines and tomb space, Pinus densiflora was distributed in the religion services space and transposition and Alnus japonica was distributed in the entry space. By the present status of vegetation in Taeneung, the Pinus densiflora forest was the widest area with 50.3% with the broadleaf forest at 33.7%. Quercus aliena, Quercus acutissima, and Quercus mongolica were the main species found in Taeneung. The planting area was 7.9% and Pinus densiflora were the main species planted. To analyze the plant community structure of Taeneung, 108 plots were set and divided into four spaces. The importance of the percentage of those districts was analyzed on a spatial basis and it was found that the current dominant species of the tomb space was Pinus densiflora. However, as Pinus densiflora began dying out, the power of Quercus acutissima increased and an ecological succession from the Pinus densiflora forest to Quercus aliena forest was made. In the spaces of religious services and transposition, Pinus densiflora was decreasing and Quercus spp. was expanded. In the space of entry, the dominant species were Pinus densiflora and Quercus aliena, Pinus densiflora and Quercus aliena. As soil of this area is argillaceous, Pinus densiflora is expected to disappear in the end. The prior vegetation(assumed) and present vegetation of Taeneung were compared and analyzed and a goal of vegetation management and the way in which to manage vegetation were suggested. The goal of vegetation landscape management was to analyze ecological characteristics and vegetation changes, maintain and restore a landscape suitable for historical landscape forests by space. About the space of the tomb, Pinus densiflora forests and Pinus densiflora planting zones forests should be maintained and there should be efforts to restore and manage the Pinus densiflora forests, instead of the Quercus spp. forests. About the space of religious services, Pinus densiflora forests and Pinus densiflora planting zones should be maintained and managed and there should be efforts to restore and manage Pinus densiflora forests to replace Quercus spp. Pinus densiflora forests in the space of transposition should be maintained and managed and Pinus densiflora forests should be restored to replace Quercus spp. trees. Alnus japonica forests should be restored in the space of entry.

한국을 비롯하여 논농사 중심지역에서는 하천 주변이 과거에는 농경지로, 그리고 오늘날은 도시지역으로 개발되어 하천의 원형이 거의 유지되지 못하고 있다. 하천은 수역과 수변으로부터 거리에 따라 여러 개의 이질적 생태적 공간이 이어지는 복합생태계로서 하나의 경관으로 볼 수 있다. 하천이 하나의 온전한 생태적 계로서 기능을 발휘하기 위해서는 이들을 모두 포함하는 하천의 원형이 복원되어야 한다. 현존하는 하천복원사업이 수변 구역의 복원에 초점을 맞추고 있지만, 진정한 복원이 이루어지기 위해서는 온전한 강변 식생의 복원이 선결과제이다. 본 연구에서는 유적군락의 형태로 잔존하는 강변 식생을 조사하여 식생복원 모델로 삼고자 한다. 수위와 침수체제에 의해 하천의 횡단구조를 수변, 홍수터 및 제방으로 구분한 후 각 지소의 적합한 식생단위를 구분하여 생태적 복원을 실현하기 위한 정보를 구축하였다. 수변식생으로는 달뿌리풀군락과 갈대군락이 자주 출현하고, 홍수터에는 갯버들군락과 키버들군락이 우세하였다. 그 중 전자의 식물군락은 하상재료가 거친 입자의 지소에 성립하고, 후자의 것은 미세한 입자의 지소에 성립하는 경향이었다. 제방역에는 버드나무군락, 다릅나무군락, 귀룽나무군락, 물푸레나무군락, 산사나무군락, 신나무군락(한탄강 지류), 참느릅나무군락, 물푸레나무-갈참나무군락(한탄강 본류), 오리나무군락(민통선 북방지역), 소나무군락, 황철나무군락, 느릅나무군락(소양강 상류), 왕버들군락(금강 중류) 등이 성립하였다. 이러한 식생정보를 하천의 지리적인 위치에 따라 구분하였고, 생태적 복원 시 도입식물을 결정하기 위한 자료로 삼기 위해 각 식생단위를 이루는 종 조성을 정보 체계화하였다.을 효율적으로 하기 위하여 Solar Unit으로부터 나오는 전기를 중전기에서 밧데리로 축전을 시키고 완전 충전 후에는 나머지 전기는 방전이 되도록 회로를 구성하였다. 사통수문 자원조사 결과에 의하면 현재 저수지에 물공급을 하는 수문은 취수탑 형식이 70% 이상을 차지하고 있으며 나머지 30%의 사통수문 중 원형수문비가 98% 이상을 차지하고 있다. 현재 대체에너지를 사용하는 저수지 사통수문은 없는 것으로 조사되었으며 전력을 사용하는 사통도 조사결과에 의하면 20% 이내로 나타났다. 이러한 결과는 향후 수리시설 개보수시 적은 예산으로 사업을 시행하는 경우 사통수문의 설치방향의 지표가 될 것으로 판단되며 수리시설의 운영관리에 대한 새로운 대안으로 제시할 수 있다.분류되었다. 지표 유거가 많아 배수등급이 매우양호로 분류되던 토양은 정 등(1995)의 분류와 비교하여 대부분 강우 유출 가능성이 큰 쪽으로 조정되었다. 새로운 수문학적 토양유형을 이용할 경우 낮은 토심에서 암반층이 발견되는 산림토양이 분포한 유역이나 산림, 밭 등에 식질 토양이 많이 분포하는 유역에서는 기존의 방법을 이용하는 것보다 강우 유출량이 높게 평가될 것으로 판단된다. 앞으로 강우 유출량 실측자료와의 비교를 통해 지속적인 보정을 하여야 할 것이며 특히 불투수층의 존재시 일괄적으로 D유형으로 분류된 토양의 경우 깊이에 따라 C 또는 D 유형으로 세분하여 조정할 필요가 있다.가 있었다. 에틸아세테이트분회물의 경우 디글로로메탄 분회물에 비해 다소 낮은 저해효과를 나타내었지만 250 ${\mu}$g/ml 농도에서 약 60%의 세포독성 효과를 나타내었다. 디클로로메탄 분획물과 에틸아세테이트 분

This study is basic research which aims to compare and analyze changes in rural areas in modern times. The main purpose of this study is to comprehend the characteristics of changes in the Korean rural landscape and to suggest the implications for preservation and maintenance of the rural landscape. To help in understanding the rural landscape systematically, it should be divided into six types: housing landscape, cultivation landscape, green landscape, waterside landscape, streetscape and symbolic and religious landscape. According to this step, the contents and the procedures of changes were analyzed generally. Based on the literature review and field survey, the styles of changes were deduced to be formation, alternation, relocation, damage and restoration on landscape elements. Lastly, it was concluded that complex changes of landscape in rural areas from the government's development policy have been continued from macroscopic changes like overall structure and system of landscape to microscopic changes like shape, material, size and color of each landscape element. Rural villages which have not had the government's development policy applied to them may not be appropriate for this study. However, this study has significance in that it can suggest the direction for desirable rural planning. Future studies need to consider landscape change through not only the development policy but also economic, social and cultural factors.

우리나라는 계절에 따라 수량의 변화가 커서 하천에 흐르는 유량의 변화가 심하지만 대부분의 하천은 갈수기에도 각각 일정량의 유량을 가지고 흘러간다. 그러나 충적층을 통과하는 소하천의 경우에는 계절에 상관없이 하천수가 지하로 침투하여 지표수가 감소한다. 소하천의 하천수량이 갈소되거나 건천화 될 경우 수질이 악화되거나 하천의 바닥이 드러날 경우 수중생태계는 파괴됨 것이다. 현재 지하수를 개발하여 부족한 하천수를 보충하는 방법을 모색하고 있으나 하천수의 지하침투가 심각한 경우에는 지하수만으로는 하천수의 부족분을 보충하는데 한계가 있다. 충적층을 통과하는 소하천의 침투수를 차단하는 방법으로 충적층에 불투수 매트를 설치하여 사용하면 하천의 건천화를 방지할 수 있으며, 충적층의 침투수를 차단하기 위하여 충적층위에 점토층을 설치하여 투수계수를 저하시키는 방법을 사용하면 부족한 하천유지용수를 확보할 수 있다. 따라서 충적층을 통과하는 소하천의 건천화를 방지하고 자연형 하천으로 개발할 경우 수중생태계 복원성이 우수하며, 자연경관의 복원에도 효과가 있다.

2005년 10월 서울시는 47년 만에 청계천을 약 5.8km 구간에 걸쳐 정비하여 서울중심에 새로운 물길을 열었다. 청계천의 경관조명은 청계천의 남북을 이어주는 22개의 다리, 청계천을 동서로 가로지르는 산책로를 비롯하여 다양한 청계천 주변 요소에 청계천을 이용하는 보행자들을 위한 경관조명을 복원되는 전 구간(5.8km)에 약40억을 들여 설치하였다. 이중 산책로는 보행자가 가장 많이 이용하는 요소이며, 청계천의 주변 경관에 다채로운 야경을 연출하여 청계천에 아이덴티티와 방향성을 지니게 하고 야간에 산책로를 이용하는 보행자들에게 즐거움과 여유로움을 주고 있다. 이에 본 연구는 도심내 수변가로로 대표되는 청계천 산책로를 대상으로 조명환경의 특성을 분석하였다. 이를 위하여 산책로에 대하여 수평면조도를 측정하고 기준값과 비교하였다. 조도의 특성을 분석한 결과 청계광장 산책로 입구, 광통교 밑부분, 산책로와 연결되는 4곳의 계단 등이 KS기준조도와 비교하여 부족한 것으로 나타났다. 산책로의 경우 수평면조도에 문제가 없는 것으로 분석되었지만 주거지역의 경우에만 일부분 기준조도에 비해 부족한 것으로 나타났다.

본 연구에서는 자연하상 복원을 위한 하상복원공법을 개발하여 시험구간에 적용하였다. 공법적용 대상 지역은 안양시역내의 안양천 일정구간으로 화창교로부터 상류방향으로 약 500m 거리에 웅덩이 수제공법이 적용되어 있으며, 그로부터 다시 상류방향으로 130m 떨어진 거리에 낮은 바닥막이 공법이 적용되어 있다. 낮은 바닥막이 공법의 경우 완만한 곡류사주의 직상류 부로서 강한 수류와 함께 빠른 유속이 형성될 경우 하상의 세굴이 예상되어 이를 방지하기 위해 저수로의 유하방향으로 완만한 호형으로 설치하였으며, 웅덩이형수제 공법은 완만한 곡류로 좌안 수충부가 형성되어 있어 물의 흐름방향과 유속을 제어하여 흐름에 의한 호안침식을 방지하기 위해 현 위치를 선정 및 적용하였다. 첫 번째, 경관모니터링 결과 낮은 바닥막이 공법과 웅덩이 수제 공법을 적용한 구간에서 대규모 홍수 이후에도 저수로 호안과 하상의 안정성이 유지되었으며, 이는 공법 설치 전 후 하상 경관의 변화가 거의 없어 수리적 안정성 유지를 하고 있다고 볼 수 있다. 또한 웅덩이 수제 공법 설치 후, 미소서식처가 형성되면서 포식자인 왜가리, 백로류를 지속적으로 관찰할 수 있어 어류서식처로서의 기능이 강화되었음을 간접적으로 확인하였다. 두 번째, 생태계 모니터링 결과 저서성 무척추동물의 경우 한국오수생물지수(KSI)는 낮은 바닥막이 공법을 적용하여 하상구조가 변화된 조사 지점 st.1의 환경상태가 "양호"에서 "최적"으로 변화하였기 때문에 공법 적용이 서식처 건강성 증진에 도움을 준 것으로 판단된다. 세 번째, 수질 모니터링 결과 용존산소의 경우 상부지점보다 하부지점이 낮게 나타나는 결과를 보여주었다. 낮은 바닥막이 공법에 의한 용존산소 상승효과보다는 다양한 서식처의 제공이라는 측면이 보다 중요한 효과를 나타낸다. 결과적으로, 공법의 실용화를 위한 적용 공법에 대한 생태계 모니터링 및 평가를 통하여 하천에서의 다양한 서식처(Habitat) 창출을 통해 수생 생물의 다양성을 증진시키고, 하천 하상공법에 대한 생태계의 조사 및 평가기법을 확보하여 연구성과를 다른 하천으로의 확대 적용 할 수 있을 것으로 기대한다.

The present study has monitored the changes in the biodiversity of Dunchon-Dong ecological and landscape conservation area after the restoration of the wetland, identified and analyzed the threats to the ecosystem, and presented a management plan accordingly. In this area which was forests and rice paddies in the past, apartment reconstruction is currently underway, with some hinterland forests and wetlands remaining. When we look into the change in the floras, the total number of species was 193 in 2000 before the restoration, it decreased from 2004 to 2006, and as of 2019, it was 149, showing an increasing trend. The result of comparing the species that emerged before and after the restoration showed an increase in Cyperaceae herbs such as Carex maximowiczii and Carex dispalata growing in wetland areas within forests and Schoenoplectiella juncoides and Schoenoplectus tabernaemontani growing in areas within wetlands where shallow water is maintained. As a result of analyzing the change in the area ratio of each type of extant vegetation, the wetland native herbs formed the power at the highest ratio after the restoration. The change in the power of the wetland native herbs was on an increasing trend until 2007, after which it decreased much in 2010 and then gradually increased, showing values of 26.6% in 2000, 44.6% in 2002, 49.0% in 2005, 53.3% in 2007, 28.7% in 2010, and 37.3% in 2019. The cause of the decrease in 2010 was judged to be due to the vegetation management conducted to secure open water and remove organic matter in freshwater reservoirs. The amphibia which emerged from 2000 to 2019 was a total of 9 species including Hynobius leeshii, Bufo gargarizans, Kaloula borealis, and Rana uenoi. As a result of the changes in the emerging wild birds, the species diversity index before the restoration was 0.9922 in 2000, and the species diversity index after the restoration gradually increased to 1.2449 in 2005, 1.2467 in 2010, and 2.2631 in 2019. The amphibia and wild birds inhibiting in the Dunchon-Dong forest and wetland were judged to have increased through continuous wetland maintenance such as naturalized plant removal management, native plant maintenance, and open water securing management. For the ecosystem preservation management of the Dunchon-Dong ecological and landscape conservation area, it was suggested to minimize the impact of the Dunchon-Dong reconstruction project, reorganize the indiscriminate access roads adjacent to the wetland, and reorganize the main entrance to the wetland. For ecosystem restoration management, systematic restoration and ecological buffer planting were suggested to be carried out at the time of construction fence demolition.
